COMBINATION LATCH-LOCK AND BOLT.

Application filed. November 2-9, 193.8.

To all whom it may concern:

Be it known that I, Joi-rN GAIL WATSON, a subject of the King of GreatBritain, residing at No. 26 Alexander Parade, Clifton Hill, Victoria,Australia, have invented certain new and useful Improvements inCombination Latch-Locks and Bolts, of which the following is aspecification.

This invention has been devised to provide improvements in the designand working of latch locks by embodying with such a contrivance, slidebolt, the latter being freely usable in an unlocked condition, butlockable at any time by a. slight movement of the hand.

In order that my invention may be the more easily understood, referencewill be made to the accompanying sheet of drawings, in which Figure 1 isa view of the combination latch lock and bolt affixed in position on agate, the bolt being free to be raised by the latch arm.

Fig. 2 is a similar view of Fig. 1 with the exception that the bolthereinafter described is in a locked position, so preventing the gatebeing opened.

Figs. 3 and 4 illustrate details hereinafter to be referred to.

In a combination lock such as I have above referred to, I employ a broadlongitudinal plate. a, which, for the sake of illus tration, but not inany way to limit the size I may use, is about 6 in length by about 2 indepth and composed of metal plate of about 3/16 in thickness. he ends ofsuch plate are returned at a right angle to the front or bolt side ofsuch plate, the latter having countersunk perforations at each corner,through which screws 7) may pass to hold the plate to the woodwork c ofthe gate or door.

In the returned ends, respectively (Z, d, are perforations c, e, theformer being curved. and the latter being elongated or oval. The end (3is preferably bent parallel, the bent end 6 being secured by screws 6 tothe end face of the. gate or door, the perforations respectively beingsized to permit the operation therein of a bolt 7. The latter is formedof a longitudinal round bar of preferably about a ii in diameter andprovided in its length, within the re.- turned plate, with riveted studg, (see Fig. piece, against the bolt being drawn out through theperforation e.

Serial No. 264,570.

The end it of the bolt is U-shaped, the portion 7L being at acting as alimitation stopper against the end (Z so regulating the forwardmovementand latching position of the bolt f. The width of the flatportion 7: and space 71- equals the length of the forward or rearwardmovement of the bolt f when engaging or disengaging the slot 0 forlooking or unlocking purposes.

In the returned plate (Z a control gap 1 is cut out, so that theupwardly returned half of the bolt end may slide therein over the lowerportion of the slotted end sup porting plate, shown by dotted lines inFig. 2, thus forming a lock against movement of the bolt f eitherbackward or forward.

In the slotted end plate (Z the upper portions or bifurcations affordedby the slot are provided with perforations j so that a padlock (notshown) may be locked through either of such members to prevent the bolt7' from being withdrawn when it is desired that the gate or door shallbe locked against ingress.

[Lin opening 70 is cut through the back plate of a sufficient width topermit a curved latch arm A1 to pass in order that its clowndly curvedend may operate underneath, n lift the bolt 7" to cause the latter torock upwardly or downwardly as the exterior end f the latch is operatedby th finger and thumb of the person desiring to enter the gate or door.

A hinged plate k (see Fig. 4:) is made in dressing out the slot, by soshearing the plate that the pressed out portion points outwardly for asufficient distance to enable a'pin m, to pass through same and thelatch arm is to form a pivot on which the latch arm 71:.

ay rock. It will thus be seen that onmoving the latch arm 70 downwardfrom the outside of the gate, the bolt f will lift to an inclined anglefrom the horizontal, the elongated or oval slot 6 permitting such boltend to lift so as to clear itself from its hasp. This latter is composedof a bent metal plate a, the front portion being about two inches indepth by about one inch and half in width, and having both ends returnedto the front for an extra inch.

The hasp a is integral with the keeper place it secured to the righthand gate post by screws of. The hasp a has a slot a to convenientlyreceive the bolt, and the right end of the plate is bent outwardly andis provided with an elongated or oval shaped perforation 0 in thevertigal position to permit the passing through of, and the upwardrocking of the bolt f therein.

In practice when the appliance is being used as a latch the portion h atthe end of the bolt f is outside or to the left of the bent portion clof the back plate a, (see Fig. 1), the bolt lying in the hasp a. Whenthe finger operates the latch arm is and pushes the door inwardly, thebolt f rises from its latch and slides down to the curved front of thehasp n. When .the gate or door is slammed for closing, the bolt f risesover a the gap.

the curved front of the hasp and falls into the slot 91 and is supportedin that position.

When it is desired to lock the bolt f against intrusion, the returnedend it of the bolt is lifted up to the horizontal and is pushed along sothat the returned end hooks over the bifurcated plate d. The other endof the bolt f is thus sent into the elongated perforation 0 in the bentplate 0, the end it is then allowed to fall to a vertical position asshown in Fig. 2, the padlock may then be secured through the lowerperforation of the perforations j in the returned end of the plate (Z.

The whole of the parts hereinbefore mentioned are preferably preparedfrom wrought metal steel, cast malleable or the like material.

I claim:

1. A combination latch-lock and bolt, including a pair of platesprovided with bent ends having slots therein, a bolt movable throughsaid slots and having a U-shaped end providing a flat portion andleaving a space, the flat portion acting as a limitation stopper to thebolt for latching purposes 1,326,55&

and acting in conjunction with the space for controlling the forward andrearward movement of the bolt to engage and disengage the slot in theoutermost end piece of one of the plates.

2. A combination latch-lock and bolt, including supporting and keeperplates provided with bent ends having slots therein, one of the bentends of the supporting plate being also provided with a horizontally disposed gap, a bolt slidable in the bent ends of the plates and designedwith a flat portion at one end for passing through 8. A combinationlatch-lock and bolt, comprising a supporting plate provided with bentends, one of the bent ends having an opening and a gap therein and alsoprovided above and below the gap with padlock receiving perforations,the other bent end having a slot therein, a bolt slidable through thebent ends of the supporting plate, a keeper plate designed so that thebolt may be latched or locked therein, a rocking latch arm on thesupporting plate for operating the bolt when the bolt isin a latchedposition, a U-shaped portion at one end of the bolt having'a flattenedterminal for passing through the gap in the bent end to facilitate thearrangement of the U- shaped portion in straddled relation with the saidbent end and to hold the bolt in a locked position in the keeper.

In testimony whereof I afiiX my signature in the presence of twowitnesses.

JOHN GAIL WATSON.
